Background
The skin is the natural coat of the human body and is generally divided into three major parts, namely epidermis, dermis and subcutaneous tissue from outside to inside, and the stratum corneum which is the outermost layer of the skin plays an important role in the integrity of the barrier function of the skin. The cuticle has a sebum membrane which is a semitransparent oily membrane formed by sebum, sweat and epidermal cell secretion, free fatty acid, lactate, urea and uric acid in the sebum membrane are natural moisturizing factors and play a role in moisturizing the skin, the cuticle and the sebum membrane can prevent the moisture loss of the skin, and under the normal condition, the water content of the cuticle is about 10 percent and is lower than the level, the surface water shortage symptom can be generated.
The dry skin refers to the condition that the skin becomes thick and rough due to the reasons of water shortage and the like caused by seasonal changes; in autumn and winter, sebum and moisture secretion of human bodies are gradually reduced, the skin becomes dry obviously, particularly, the skin surface of middle-aged and old people is thicker and drier due to the great reduction of moisture, the phenomena of chapping and pruritus at hands, feet and shanks can be caused, and the phenomena of inflammation or purulence and the like caused by chapping of the skin can be caused in serious cases.
The pure cotton fabric is a natural fiber which is deeply favored by consumers, can absorb moisture into the surrounding atmosphere, has the standard moisture content of about 8 percent, and has the moisture content far lower than the requirement of normal skin of a human body on the environmental humidity in winter, so that the pure cotton fabric is easy to cause skin itch of middle-aged and elderly people and other physiological symptoms which influence the body health.
The performance of all-cotton textiles, especially underwear, as the second layer of skin of human body is closely related to the comfort and health of human body to a great extent, and the development of textiles with health care function is a new requirement of the current textile market and people for high-quality life.
Softeners are a class of chemicals that change the static and dynamic coefficients of friction of the fibers. When the dynamic and static friction coefficients of the fiber surface are changed, the resistance which needs to be overcome when the fibers and the skin move mutually can be changed, and the soft and smooth tactile effect is realized, and the tactile effect is a quality index which can be evaluated by a consumer in charge and has important influence on the sale of commodities. Soft finishing is an important after-finishing process in printing and dyeing processing. During the processing of the textile, the hand feeling of the textile becomes rough after being treated for many times, and the common synthetic fiber fabrics are worse, especially the superfine fiber fabrics. In order to make the fabric have soft, smooth and comfortable hand feeling, the fabric needs to be finished, and the finishing is widely performed by using a softening agent at present.
The product has the advantages of developing the functions of moisturizing, easy decontamination, softness and washing resistance of the all-cotton fabric, aiming at enriching the function finishing category of the cotton fabric and improving the clothing quality of the cotton fabric, and has wide development and application prospects from the current health care perspective.
